Hello guys, I'm new to drumming and this forum. Few days ago I purchased Tommy Igoe's Great Hands For Lifetime. Here is video of me playing excercises #1 to #4. I can hear that my tempo is a bit off (metronome is set to 104bpm) but I would really like to hear what do you guys think about my technique. Am I using too much wrist, too much elbow? Every critic is helpful.
